Summary on Grant Application Form |

The ultimate objective of the present proposal is to convert toxic fly ash from incinerators into a material which can be used in construction industry. The work includes the design and construction of a novel sintering/pelletis system in order to detoxify the fly ash. A key aspect of this proposal is the technique used to ensure the energy efficiency of the process. This is based on the application of a regenerative heating concept. The key parameters to be investigated in this project are: System operating conditions and design, temperature and composition distribution, decomposing conditions of dioxin/furan and fixation of heavy metals by sintering, the sinter properties eg leachability, variability of ash, investigation of heat recovery and process intensification. As a result of this research work, the toxic fly ash material which is now being landfilled at a very high cost of 300 per tonne will be converted to an innocuous product which can either be used safely by construction industry or be landfilled at a very low cost of about 30 per tonne since it has been converted to non-toxic material.
